Hi Gerrit,

As for now, multipart support is only available for requests (multipart/mixed [1], multipart/form-data [2]). Responses are limited to single parts as multipart data had not been considered in the RESTXQ specification.

It would be reasonable to also choose sequences for multipart/mixed and maps for multipart/form-data (with filenames as keys). I’ll have some more thoughts on that.

Best, Christian

I was faintly hoping that a sequence will be magically output as multipart/mixed with appropriate part content types when I annotate it with %rest:produces("multipart/mixed"):

declare %rest:GET %rest:path("/test") %rest:produces("multipart/mixed") function my:test-multipart() { (<ok/>, json:serialize(map{'some':'json'})) };

But the response header says "Content-Type: application/xml", and the result is

<ok/> { "some": "json" }

Are there some other functions or annotations or rest:response elements that I can use in order to get multipart/mixed correctly assembled? Bonus: With the possibility to add file names to each chunk?
